Replacing the naphthalene C-unit of the anti-tuberculosis drug bedaquiline with a range of bicyclic heterocycles of widely differing lipophilicity gave analogs with a 4.5-fold range in clogP values. The biological results for these compounds indicate on average a lower clogP limit of about 5.0 in this series for retention of potent inhibitory activity (MIC90s) against M.tb in culture. Some of the compounds

substituted pyridines to produce compounds with reduced lipophilicity, anticipating a reduction in half-life. While there was a direct correlation between in vitro inhibitory activity against M. tuberculosis (MIC90) and compound lipophilicity, potency only fell off sharply below a clogP of about 4.0, providing a useful lower bound for analogue design. The bulk of the compounds remained potent inhibitors
ATP 合酶抑制剂贝达喹啉对耐药结核病有效,但亲脂性极强 (clogP 7.25),血浆半衰期很长。此外,贝达喹啉抑制通过心脏 hERG 通道的钾电流,与 QT 间期延长相关,因此需要进行心血管监测。制备了类似物,其中萘 C 单元被取代的吡啶取代,产生亲脂性降低的化合物,预计半衰期会缩短。虽然针对结核分枝杆菌的体外抑制活性 (MIC90) 与化合物亲脂性之间存在直接相关性,但效力仅在 clogP 约 4.0 以下急剧下降,为类似物设计提供了有用的下限。大多数化合物仍然是 hERG 钾通道的有效抑制剂,但值得注意的例外是 IC50 值比贝达喹啉高至少 5 倍。许多化合物具有比贝达喹啉更高的清除率,但这与小鼠体内较低的血浆暴露有关,并且对于大多数化合物而言,相似或更高的 MIC 导致比贝达喹啉更低的 AUC/MIC 比率。这两种抗 hERG 效力较低的化合物表现出与贝达喹啉相似的清除率和出色的体内功效,表明对

Bedaquiline is a new drug of the diarylquinoline class that has proven to be clinically effective against drugresistant tuberculosis, but has a cardiac liability (prolongation of the QT interval) due to its potent inhibition of the cardiac potassium channel protein hERG. Bedaquiline is highly lipophilic and has an extremely long terminal half-life, so has the potential for more-than-desired accumulation in tissues during the relatively long treatment durations required to cure TB. The present work is part of a program that seeks to identify a diarylquinoline that is as potent as bedaquiline against Mycobacterium tuberculosis, with lower lipophilicity, higher clearance, and lower risk for QT prolongation. Previous work led to the identification of compounds with greatly-reduced lipophilicity compounds that retain good anti-tubercular activity in vitro and in mouse models of TB, but has not addressed the hERG blockade. We now present compounds where the C-unit naphthalene is replaced by a 3,5dialkoxy- 4-pyridyl, demonstrate more potent in vitro and in vivo anti-tubercular activity, with greatly attenuated hERG blockade. Two examples of this series are in preclinical development.
